Description:

Polysorbate 20, also known as polyoxyethylene (20) sorbitan monolaurate, is a nonionic surfactant derived from the ethoxylation of sorbitan monolaurate. It is widely used in cosmetics and personal care products as an emulsifier, solubilizer, and stabilizer. Its high Hydrophilic-Lipophilic Balance (HLB) value makes it particularly effective for creating oil-in-water emulsions.

• Facial mists and toners
• Cleansing products
• Lotions and creams
• Hair conditioners and shampoos
• Mouthwashes

Key Benefits:

• Enhances the solubility of essential oils and fragrances in aqueous formulations
